OFFICE 2 Claims.

This invention relates to certain new and useful improvements in lamp support and clamps.

The primary object of the invention is to provide a lamp support and clamp constructed in a manner whereby the support for the lamp may be freely mounted upon a table or other support and embodying a clamp whereby the lamp support may be attached to the edge of a table, desk or the like and restrained from movement.

A further object of the invention is to provide a lamp support and clamp of the foregoing character wherein a novel form of clamp device is associated with a lamp support with hand grip devices to facilitate operation of the clamp.

With the above and other objects in View that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing:-

Figure 1 is a side elevational view of a lamp support and clamp constructed in accordance with the present invention, the same being illustrated as freely mounted upon a table or other support;

Figure 2 is a bottom plan view showing the clamp arm normally confined within the hollow base of the lamp support;

Figure 3 is a vertical sectional view of the lamp support and clamp illustrated as clampingly engaged with the table edge or other support and illustrating the tensioning means and guide for the clamp; and

Figure 4 is a detail sectional View taken on line 44 of Figure 3.

Referring more in detail to the accompanying drawing, the lamp support and clamp comprises a hollow base that may be of any configuration desired, the same being illustrated as of circular formation and including a top wall 5 and a stepped annular side wall 6, a cushion gasket 1 or the like lining the lower portion of the annular side wall 6 and retained therein by a split band 8 as shown in Figures 2 and 3. A tubular standard 9 rises from the top wall 5 of the base adjacent one side thereof and carries an adjustable lamp socket ID at the upper end thereof and with which a reflector H is associated.

The connection between the tubular standard 9 and the top wall 5 of the base includes an annular flange or bead I2 spaced from the lower end of the standard and adapted to rest upon the top wall 5 of the base that surrounds an opening through which the lower end of the standard passes. A guide for a clamp leg is mounted upon the lower end of the tubular standard within the hollow base and includes an angle plate having an upper end it with an opening therein for mounting on the lower end of the tubular standard and a depending right-angularly extending leg M having an outwardly directed right angularly extending foot !5 at the lower end of the leg. An arm l6 extends through the side Wall 6 of the hollow base and the ofiset inner end ll is apertured for mounting on the lower end of the tubular standard 9. The lower end of the tubular standard 9 is externally threaded and the u jamb nut i3 threaded thereon cooperates with the 1 collar l2 at the upper side of the top wall 5 of the hollow base for clamping the angle guide and arm 1% in position as will at once be apparent from an inspection of Figure 3.

A clamp is associated with the hollow base and standard 9, the same including a vertical leg l9 slidably extending through an opening in the top wall 5 of the base adjacent the tubular standard 8, the upper end of the leg !9 having an arm 20 extending at right angles therefrom and having an opening therein through which the tubular standard passes, the arm 20 being disposed above the lower fixed arm it. The lower end of the leg l9 extends through a slotted opening in the foot E5 of the guide, the lower end of the leg l9 below the guide being bent at right angles to provide a clamping arm 2! that underlies the hollow base and is normally confined therein as shown in Figures 1 and 2. The clamping arm 2| is covered by felt 22 or similar material for cooperation with the lower projecting edge of the packing 1 within the hollow base to prevent injury to polished surfaces or the like, upon which the clamp support is placed or with which the clamp is engaged. The clamping arm 2! is tensioned by means of a coil spring 23 located in the lower end of the tubular standard 9, the upper end of the spring 23 being secured to a pin 24 that extends transversely of the tubular standard it to project outwardly thereof to act as a stop for upward movement of the arm 20 at the upper end of the clamp leg it. The lower end of the spring 23 is anchored to a finger 25 struck out from the lower end of the leg l9 beneath the guide foot l5.

When the support alone for the lamp is used, as illustrated in Figure 1, the spring 23 moves the clamping arm 2! into the hollow base of the lamp support, the latter being mounted upon a table or other support T, the lower projecting edge of the gasket 1 confined within the annular wall 6 of the hollow base and the felt covering 22 upon the clamping arm 2| preventing injury to the finished surface of the table or support. When it is desired to use the clamp for the mounting of the lamp, the arms I6 and 20 are gripped, the latter being lowered. against the tension of the spring 23 to the positions shown in Figures 3 and 4 for clamping engagement with an edge E of a table or other support, the hollow base resting upon the upper surface of the edge E while the clamping arm 2| is engaged with the lower surface of the edge E. The clamping arm is accurately guided in its movement by the mounting of the operating arm 2!! upon the tubular standard 9 and the passage of the leg I9 of the clamp through the slotted foot l5 of the angle guide. The pin 24 to which the upper end of the spring 23 is anchored constitutes a stop to be engaged by the arm 20 for limiting upward movement of the clamping leg l9 and clamping arm 2| into the hollow base of the support.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent and while there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

I claim:

1. In a lamp support and clamp, a hollow base, a tubular standard rising therefrom and adjustably supporting a lamp socket and reflector at the upper end thereof, a clamp having a vertical leg slidable through the top wall of the base, a horizontal arm at the upper end of the leg slidable upon the standard, a clamping arm extending angularly from the lower end of the leg, a

guide for the lower end of the leg anchored on the lower end of the tubular standard within the hollow base, a spring associated with the clamping arm for normally influencing the same in an upward direction towards the hollow base, the guide being of angular formation with one end secured to the lower end of the tubular standard, a slotted foot projecting from the other end of the guide and through which the vertical leg extends and the latter moving in frictional contact with the guide intermedate the upper and lower ends thereof.

2. In a lamp support and clamp, a hollow base, a tubular standard rising therefrom and adjustably supporting a lamp socket and reflector at the upper end thereof, a clamp having a vertical leg slidable through the top wall of the base, a horizontal arm at the upper end of the leg slidable upon the standard, a clamping arm extending angularly from the lower end of the leg, a guide for the lower end of the leg anchored on the lower end of the tubular standard within the hollow base, a spring within the tubular standard for normally influencing the clamping arm in an upward direction towards the hollow base, the

guide being of angular formation with one end secured to the lower end of the tubular standard, a slotted foot projecting from the other end of the guide and through which the vertical leg extends and the latter moving in frictional contact with the guide intermediate the upper and lower ends thereof, the upper end of the spring being anchored to a pin projecting from the standard to form a stop for the arm at the upper end of the leg and a finger struck out from the lower end of the leg and to which the lower end of the spring is attached.
